brother you are lucky, a few rules to follow especially if you are in a foreign country,
1. never do it in their home tuft,esp in china where it is considered "illegal"
you could be set up, when some one can come in and claim that it is his wife you are involved .Or claim he is gong an and that you committed an illegal act and henceforth blackmail you for money.
2. never do it in your own tuft too,if you are staying in a private residence. as the girl could set you up like in condition 1 since they can trace you, so someone can come along another day, ambush you, claim the same thing and black mail you again.
3. a hotel will be neutral ground where it is more difficult for them to set you up and there is always hotel security to call for assistance.
4. don't be a cheapo pay for the services, offers of free services always end up more costly later,( unless you really fell in love and want to enter into a serious relationship.....good luck then!) otherwise mantain it as an business like transaction, no strings attached.

lastly practise safe sex.
enjoy...........
